摘要：

The observation of failure patterns of different reinforced concrete structures due to earthquakes in several countries has caused critical concern about the performance of beam-column joints. Retrofitting of reinforced concrete (RC) structures can lead to increased stiffness, strength, and failure deformation. This paper introduces a new type of reinforcement detail for the RC jacketing of nonductile exterior beam-column joints. Experimental investigations were carried out on five types of joint specimens keeping a scale ratio of three and were subjected to reverse cyclic loading. The improvement in performance was observed for the retrofitted non ductile exterior beam-column joints using the new RC jacketing than the conventional RC jacketing.
